6 Claims.

, My invention relates to an apparatus for applying waxes, resins, rosins, solubilized cellulose, oils, or similar substances, to natural or artificial t textile fibers and artificial silks'.

An object of my invention is to provide an apparatus by means of which such materials may 4be applied in the liquid form, melted if expedient, or emulsifled in water, or dissolved in a nonaqueous volatile or non-volatile solvent, such as carbon tetrachloride, ethylene dichloride, xylene, acetone, gasoline, alcohol, Stoddard solvent, glycols, organic acetates, or similar solvents.

A further object of. my invention is to provide an apparatus by means of which the processes and results claimed and described in my-pending United States application, filed April l1, 1932, Serial Number 604,647, may be accomplished, or carried out'. f

Broadly, my invention comprises a centrifuge n provided with means for removably securing the materials to be sized therein, a storage tank for the supply of the sizing materials, means for conveying, or conducting, the sizing materials to the centrifuge, means for extracting the excess, or surplus, sizing material from the centrifuge and from the material being sized, and'means for recovering the non-aqueous volatile solvent, when such is used. y vA preferred embodiment of my invention is 30 illustrated in the accompanying drawing, but I do not confine myself to this exact arrangement or construction.

'Ihe centrifuge I is provided with the basket 2, composed of woven wire, or suitable perforated 35 metal, which is drivenvby means of the gears 3 and 4 'and shafts 5 and 6. The material to be treated is placed within the rotatable basket 2 and properly packed therein. For purposes of illustration, I have shown the yarn 'I wound on spools 8, but the material may be in the form of skeins, bundles, packages, or wound on Ibobbins, or other suitable carriers, or the material may be packaged fibers or woven fabric. The liquid sizing material is stored in the tank S and is conveyed through a suitable filter I0 to the centrifuge I, by means of the pipes II, I2, and' I3. 'Ihe pipe I3 is also connected to the return pump I4, from which the sizing material is returned to the storage tank 8, through the pipe I5. The tank 8 and centrifuge I may require air vents and when volatile solvents are used, these may need to be surrounded with a water jacket. It may be advantageous to have the pipe I3 lead to a storage tank of greater capacity. than thecentrifuge and 55 from which the pump u draws. The centrifuge Pawtucket, B. I.

This application July 24,

I and tank 8 are provided with steam jacketed chambers I6 and Il, respectively, in which steam, if needed, is circulated for maintaining the sizing material in liquid form, by means of the steam supply pipes I8 and I9 and the return pipes 20 and 2I. Some, or all of the piping may require heating jackets, depending upon conditions, and. the sizing used. Other means of supplying heat may be employed, as for example, electrical heat units. An overflow pipe 22 leads from a point near the top of= the centrifuge I to the pipe I3 belowi the pipe I2. A shut-off valve 23 is located in the pipe I 3 between the pipe I2 and the pipe 22. 'I'here is also a shut-off valve 24 in the pipe I2. For the purpose of recovering non-aqueous volatile solvents, when such are used, air is drawn into the centrifuge I through the pipe 25. The

valve 26 inthe return pipe I5 is closed, and the solvent conveyed through the pipe 21, condenser 28 and pipe 29 to the receiver 30. To prevent excessive loss of the solvent, when a solvent is needed, the centrifuge I and tank 9 are fitted with the water-jacketed covers 3i and 32. The

valve 33 in the pipe 2l is used for closing the pipe A 2l when waxes, resins, etc., are used in liquid form, without being dissolved in non-aqueous volatile solvents.

En operation, if it is desired to size the material with waxes, solubilized cellulose, resins, rosins,A

animal, vegetable, or mineral oils, or materials having similar properties, in liquid form, the basket 2 is loaded, the valve 23 closed, and the valve 24 opened, and the centrifuge filled with the sizing material from the tank 9. During this process, the basket may be revolved slowly, if desired, -to aid the assimilation of the size. When the material has been thoroughly impregnated with the size, the valves 24 and 33 are closed, the valves 23 and 26 opened, and the pump I4 operated to drain the centrifuge I. The basket 2 is then rotated rapidly to remove the excess sizing material.

When the sizing materials are dissolved In a non-aqueous volatile solvent, the process is the same, except that after the excess solvent mixture has been removed by centrifuging the solvent retained in the yarn -may be recovered by evaporation and condensation. The .basket 2.is revolved, air is admitted through the pipe 25; the valve 26 is closed and thevalve .23 opened, and the recovered evaporated solvent is drawn through the pipes I 3 by the pump I4, through the pipe 21 into the condenser 28, where it is condensed, and from thence, it is led through the pipe 29 into the receiver 30.

` out, heat in. the steam chambers of the centrifuge and storage tank, depending upon the temperature required to maintain the sizing solution in a liquid and free owing condition. Y

Yarns prepared, in the manner described, may be ined as warp yarn, without additional sizing, or as yarn for spinning direct to the weaving or shuttle bobbins, without the necessity or rst spinning onto an intermediate bobbin, then reu winding on spools and again re-winding onto weaving or shuttle bobbins, as is the' practice at present. Thus, a large saving in labor and nia-- chinery is accomplished' by the use oi this apparatus. The use of expensive humidiiying equipment is also eliminated.

The waxes usedas size on the yarn may be recovered from the woven cloth by use of volatile solvents.4 Thus, the cost of sizing material is negligible, whereas the materials now in use for this purpose are much more expensive in initial y cost, and are'lost in the nnisiiing operations.

Some oi the advantages of my invention are: Yarnvproperly treated may be prepared in this machine for warp or filling yarn. It is possible to stretch the yarn in later processes. The yarnv will stand manufacturing abuse.

This machine would take the place of the familiar slashing machine.

i Yarn, thus prepared, will make unnecessary` the use of the customary humidiying machines.

The yarn, properly prepared, may be spun di rectly to shuttle or weaving bobbins, without the necessity oi.' first winding to intermedia bobbins and then making use of expensive re-winding machinery. y

The waxes used may be recovered and used over, whereas the sizes, in use today', are lost in the nnlshingope'rations. Meltecl waxes may be applied, without volatile solvents being used.

A ber sizing apparatus comprising a centrifuge member, a supply tank for sizing material dissolvedin a solvent, a pipe connection between the centrifuge and the supply tank for returning the excess material, a pump in the pipe connection, an overflowpipe connecting the' centrifuge-and the return pipe, 'and means con nected between said centrifuge and said supply tank for diverting,evaporating and condensing the surplus solvent and collecting the same.
